"We were pleased to announce an important new clinical study and an expanded agreement as part of our collaboration with the Lung Cancer Initiative at Johnson & Johnson and we believe these announcements reflect the progress we have made in our strategic collaboration with LCI and the potential impact of real-time in vivo cellular imaging with Cellvizio, combined with the Monarch Platform, particularly as it relates to using Cellvizio for real-time tool-in-lesion confirmation during robotic-assisted bronchoscopy procedures. We were also pleased to announce the execution of equity subscription agreements with JJDC, our largest existing shareholder, and a new investor, Armistice Capital Master Fund Ltd. The proceeds from this offering will help us execute our strategic growth initiatives, including the expansion of our Cellvizio® real-time in vivo cellular imaging platform, and our goal of improving patient care in the years to come."
